Abstract:

In this study, six different macroporous adsorption resins were evaluated for their use to purify polyphenols from
Aronia melanocarpa berries. Macroporous resin XAD-7 was selected as the most suitable one. The purification parameters
optimized by static adsorption and desorption tests were as follows: adsorption and desorption time, 4 and 2 h, respectively;
sample concentration, 3.6 mg/mL; sample pH, 4; and desorption solvent, 95% ethanol (pH 7). The best purification
parameters optimized by dynamic adsorption and desorption tests were as follows: sample loading amount, 560 mL; flow
rate, 2 mL/min; washing the column with 350 mL of water; and subsequent elution with an eluent volume of 300 mL at
2 mL/min flow rate. Under these conditions, the purity of polyphenols from A. melanocarpa was improved from 11.62% to
64.37%, indicating that macroporous resin XAD-7 has a better effect in purifying polyphenols from A. melancarpa.
